when I had a "deja-vu" moment, recalling that I went down this road a few years and a few tinycore versions ago, and after much frustration figured out the problem: lzop.tcz in newbielink:http://repo.tinycorelinux.net/8.x/x86/tcz/ [nonactive]is an ARM binary! And it seems like I remember having posted back then. Now I understand how mistakes can happen, but I am surprised this has not been fixed after all these years.

Sorry, but I don't know my way around to fix it myself. I found the statically compiled lzop that I used last time around and will use it again for a workaround.
